T 0 all 107mm it may concern:

Be. it known that I, CLARENCE W. Fox, of

Saugus, in the county of-Essex and State of Massachusetts, have invented certain new ,5 and useful Improvements in Nursing-Bottles,

of which the following is a specification.

This invention has relation to elastic caps for receptacles and especially to nipples for nursing bottles.

The object of this invention is to provide improved means for fastening an elastic cap or nipple to, the month of the receptacle which upon the accompanying drawings is in the form of a musing bottle. The means 5 herein employed to fasten the cap to the re ceptacle comprise a rim formed on and surrounding the mouth of the ca a li formed on and surrounding the mout of t e receptacle, and a metallic ring adapted to be slipped over the rim of the cap and to surround the ca between its rim and the li of the receptacie. The ring is preferably eft upon and encircling the neck of the recept-acle at all times, and when slipped over the zs cap when the latter is placed upon the rece ftacle, its function is to cooperate with the hp formed on the receptacle to bind upon the intervening portion of the cap, and so to prevent aceidental removal of the same from the receptacle.

In order to slip the ring upon that portion of the cap which encircles the neck of the receptacle, it is necessary to stretch or expand the ring, or to compress the rim on the ca This operation is more or less difficult, and in order to obviate the diiliculty, I'fornr the neck of the receptacle in the present invention with a relatively greater portion near the mouth, a relatively smaller portion be- 40 tween it and the body of the receptacle, a shoulder between these relatively greater and smaller portions, and the customary out wardly bulging li surrounding the mouth of the neck. The distance to which the afore .5 said greater portion of the neck extends back from the mouth is only sufficient to afford a convenient bearing for that portion of the cap which is to receive the metallic ring. B

reason of this formation the neck of the re-' ceptacle, a metallic ring which is slightly larger than the. large portion of the neck, and yet smaller than the lip surrounding the mouth of the receptacle, may be very easily slip ed over the run surrounding the niouth oft e cap when the latter is drawn upon the neck of the receptacle so far as to encircle the small part of the neck.

7 lfte'r having drawn the cap on to the neck of the receptacle as far as hereinbefore specified, and having slipped the ring over the rim surrounding the month of the cap, the cap may then be withdrawn so far as to cause the said rim of the cap to ride up on the shoulder of the rece tacle and to surround the large portion of t 1e neck. In this position the external diameter of the rim surroundin the mouth of the cap is distended beyond the diameter of the metallic and in as much as the lip surrounding the mouth of the receptacle is of greater diameter than the ring, it 1s obvious that the ring is firmly confined between the lip and the rim, so as to lock the cap in place.

' Referring now to the accompanying drawings forming a part of this specification,

Figure'l is an elevation of the upper ortion ofa receptacle having a neck forme in accordance with this invention. Fi 2 is a similar view-with an addition of an elastic cap or nipple installed thereon in its rimary S0 osition and surrounded by a metal ic ring. ig. 3 is a view similar to Fig. 2 excepting that the cap is moved to its final position. Fig. 4 is a perspective view of the metallic rin The same reference characters indicate the same parts wherever they occur.

On the drawings 10 re )resents a receptacle which in this case has the form of a nursing bottle. The receptacle is provided with a. neck comprising a relatively greater portion 11 near and surrounding the mouth 12, and a relatively smaller portion 13 between the portion 1 1 and the body of the receptacle} 14 is ashoulder intervening between the greater and smaller portions of the neck, and is preferably formed so as to taper away from the mouth of the receptacie for a purpose hereinafter explained.

15 is an outwardly bulging or lateral lip I00 surrounding the portion 11 at the mouth of the receptacle. It will be seen therefore, that the neck comprises portions of three different diameters, namely, the smaller portion 13, the enlargement 11 and the lip 15.

16 is a metallic ring which is adapted to loosely encircle the neck of the reee)tac le, and which is preferably left remaining t iereon at all times, so as to obviate the liability of its becoming mislaid.- The said ring as 11 4.1. Hm, .M,

i E I g, t i

I shown by Fig. 4, is split, that is, it is a strip sary to this invention that the ring should be expansible. It, however, is cheaper and .easier to form the ring in this manner andto place it upon the completed receptacle than to. braze or otherwise connect the ends of the ring, or to form the lip 15 on the bottle after the ring has been placed upon the neck. The internal diameter of the ring 16 is less than the external diameter of the lip 15 but slightly reater than the external diameter of the enIargement 11 of the receptacle.

17 is a n1 ple or cap composed of elastic material suc as soft rubber. The said cap has a mouth 18 at one end, and a reduced portion 19 approximately midway between its ends. 20 is an outwardly bulging rim formed upon and surrounding the mouth 18 of the cap. The internal diameter of the moLth 18 is normally slightly less than the external diameter of the portion 13 of the receptacle.

When the cap 17 is to be placed upon the neck of the receptacle, the mouth 18 is distended and drawn over the neck as far as to cause the rim 20 of the cap to pass beyond the shoulder14 and surround the'smaller portion 13. It is to be assumed that the ring 16 is meanwhile surrounding the portion 13 so far below the shoulder 14 as not to interfere with the St)pli08.tl0n of the cap.

.The formation of the mm 20 is preferably such that when the rim closely surrounds the portion 13, its external diameter is notappreciably greater than the internal diameter of the ring 16. It is obvious, therefore, that when the cap and Tim 2O occupy the positions just described, the ring 16 may be ver easily slipped over the rim 20 so as to encircle the portion 21 intervening between said lip and the reduced portion 19, and surrounding the enlargement 11 of the receptacle (see Fig. 2). After having placed the ring as just dcscribed, it may be securel confined in that position by withdrawing the cap 17 from the neck of the receptacle as far as to cause the rim 20 to ride up over the shoulder 14 and surround the portion 11. When so positioned, the parts are related as shown by Fig. 3. B reference to the drawing it ma be seen t at although the ring 16 may not bind tightly upon the ortion 21 of the cap when the parts are in t ieir final position, still the said ring is positively confined by and. between the rim 20 and that portion of the cap which surrounds the lip 15 of the rece tacle.

By virtue ofthe herein described ormation of the receptacle and the cap, the latter ma be fastened in its place on the'former wit the greatest facility, and yet although the ring 16 does not necessarily bind the ca tightly about the neck of the receptacle, 1t

holds the same in a position from which it is absolutely impossible to remove the cap described, the 16 under normal condi tions does not ahrade or in any way unduly wear aw.y or cut the surface of the cap where it makes contact therewith.

As hereinbefo-re mentioned, the ring 16 may be continuous, and it and the exterior of the neck are not limited to any precise shape, although if-or ordinary use they would preferably be circular. It is conceivable that, for example, they might be elliptical or any other irreguiar shape As will be readily understood, the ring 16, if continuous as above mentioned, would be absolutely non-elastic. Although it is illustrated as disconnected ends, such construction is provided solely for the purpose of convenience in assembling the ring and bottle. when the parts have been as scmbled, any elasticity that might be pos- Another important feasessed by the ring possesses no utility. There fore it is to be understood that the term non-elastic employed in the claims is to be construed as meaning that the ring isnot elastic for the pu rpose of holding the nipple in place because. after assembling the parts no elasticity of the ring is needed or desired. Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set Earth all of the forms in which it may be made, or all of the modes of its use, I declare .that what I claim is The combination with a bottle, of a nonelastic ring permanently located on the neck of the bottle and adapted to clamp the mouth of an elastic cap surrounding sald neck, the neck of the bottle having three portions of distinctly different sizes so graduated that the largest of these portions, namely a lip, is nearest the mouth, the intermediate portion next to the lip, the smallest portion farthest from the lip, and a shoulder intervening between the intermediate and smallest portions whereb i the ring may he slipped over the edge of 3118 cap while said edge and the ring surround the smaller portion of the ,neck, and the cap and ring maybe then WVitnesses:
